What is polished concrete? Polishing concrete is similar to sanding wood. Using progressively finer grits of diamond impregnated segments or disks, similar to sandpaper, the concrete is steadily ground down to the desired degree of polish. A polished concrete floor has a sleek, reflective finish to it.
